Embodiment approach 1

[0018] see figure 2 with image 3 , the first implementation mode of the present invention can be briefly described as: if the user access domain is its home domain, the request and response messages are obtained through the interface set between the access management functional entity and the newly added network user positioning functional entity The location information of the user access authorization functional entity corresponding to the user, so as to realize the positioning of the user access authorization functional entity.

[0019] If the user access domain is its home domain, the method for locating the user access authorization functional entity in the NASS of the present invention is used to locate the user access authorization functional entity, including the following steps:

[0020] (1) The AMF receives an access request message from the user;

[0021] (2) The AMF analyzes that the user belongs to the management domain according to the relevant information su...

Embodiment approach 2

[0028] see figure 2 with image 3 , the second embodiment of the present invention can be briefly described as: when the user's access domain is different from its home domain, through the interface between the access management functional entity of the user's home domain and the newly added network user location functional entity The request and response messages acquire the location information of the user access authorization functional entity corresponding to the user, so as to realize the positioning of the user access authorization functional entity.

[0029] If the user access domain is different from its home domain, the method for locating the user access authorization functional entity in the NASS of the present invention is used to locate the user access authorization functional entity, including the following steps:

[0030] (1) The AMF in the user access domain receives an access request message from the user;

[0031] (2) The AMF in the user access domain anal...

Abstract

The invention discloses a method for locating a user access authorization functional entity in a NASS, and belongs to the technical field of next-generation network mobile communication. The method for locating the user access authorization functional entity in the NASS of the present invention is specifically, in the NASS, the AMF is connected to one or more newly added N-SLFs through an interface, and the N-SLF stores the location information of the UAAF and information describing the corresponding relationship between the user identifier and the UAAF location information; after receiving the user access request message sent by the requesting party, the AMF in the user's home domain sends to the N-SLF through the interface to obtain the user's corresponding A request for location information of the UAAF, the N-SLF searches for the location information of the UAAF corresponding to the user according to the correspondence between the user identifier in the user access request message and the location information of the UAAF, and responds to the user with the search result The AMF of the home domain, so as to realize the positioning of the UAAF.

Description

technical field [0001] The present invention relates to the technical field of next generation network (NGN, Next Generation Network) mobile communication, in particular to the network attachment subsystem (NASS, Network Attachment Subsystem), the access management function entity (AMF, Access Management Function) to identify user access The method of entering the authorization function entity (UAAF, User Access Authorization Function). Background technique [0002] At present, new technologies represented by the Internet are profoundly affecting the concept and system of traditional telecommunication networks, and the next-generation network is one of the highlights that attract the most attention. In the current NGN architecture, such as figure 1 The main functions of the shown NASS are the dynamic allocation of Internet Protocol (IP) addresses and other terminal configuration parameters, authentication and authentication of users at the IP layer during or before the IP a...
